Goats and Coffee

OK, this post is way off normal topics. Last month my wife and I were part of a team that visited a non-government organization working on economic development in Guatemala. The project related to raising goats and fighting the coffee rust fungus that's been causing so many problems in Central America.
I put together a writeup that gives more background on the problem and how it's being approached: www.rothweiler.us/guatemala-2014 .
It's outside my area of expertise, but looks like an interesting approach that makes good use of local resources. Comments (positive or negative) from folks with more experience are welcome.
